. NOTE : The instructions given in this Service Bulletin are only applicable to the systems and parts installed at the time of delivery of the aircraft or as changed by Bombardier Aerospace Service Bulletin(s). Before you do this bulletin, examine all STC, STA or equivalent action changes to make sure that this bulletin can be completed.

B. Reason Several cases have been reported where fluid from the aft fuel tank drain was found to run back along the center line of the aircraft and entered the aft equipment bay via the slot in the door latch mechanism. This Service Bulletin provides instructions to install a cover to the aft equipment bay door latch mechanism. This modification will reduce the risk of drain mast fluids from entering and accumulating in the aft equipment bay. C. Description This Service Bulletin gives instructions to:

–Remove the aft equipment-compartment door,

–Do the modification to the door,

–Install the door, and

–Do the necessary tests to make sure that the system operates correctly.MODEL BD-700-1A10 (BD-700)
